Acurx updates Phase 3 readiness for ibezapolstat in C. difficile Infection

Acurx (ACXP) Pharmaceuticals announced updates on Phase 3 Readiness for Ibezapolstat in C. difficile Infection based on recent FDA and EMA communications. Acurx’s Executive Chairman, Bob DeLuccia, stated: “We are very pleased with these latest favorable communications from both regulatory agencies and in our opinion are a testament to the strength of our clinical data to date, our robust regulatory submissions, and adherence to current regulatory guidance.” He further added: “We anticipate, and are confident, that with final EMA advice for our ibezapolstat Phase 3 trials for adult patients with CDI and the pediatric development plans from both regulatory agencies, Acurx will have a clear international roadmap for conduct of our Phase 3 program and, if successful, requirements for US NDA submission and EU Marketing Authorization.” Acurx has previously announced that it had a successful FDA End-of-Phase 2 Meeting and Phase 3 Readiness for ibezapolstat for the Treatment of C. difficile Infection. Agreement with FDA was reached on key elements to move forward with its international Phase 3 clinical trial program. Agreement was also reached with FDA on the complete non-clinical and clinical development plan for filing of a New Drug Application for marketing approval. Planning continues to advance ibezapolstat into international Phase 3 clinical trials for treatment of C. difficile Infection. Acurx is also preparing to submit requests for regulatory guidance to initiate clinical trials in the European Union, to be followed by requests to be submitted in the United Kingdom, Japan and Canada. Key elements for the two Phase 3, non-inferiority, pivotal trials were confirmed and included agreement on the protocol design, patient population, primary and secondary endpoints, and size of the registration safety database. Based on FDA recommendations, and in anticipation of an EMA Scientific Advice Meeting, the primary efficacy analysis will be performed using a Modified Intent-To-reat population consistent with EMA requirements. This will result in an estimated 450 subjects in the mITT population, randomized in a 1:1 ratio to either ibezapolstat or standard-of-care vancomycin, enrolled into the initial Phase 3 trial. The trial design not only allows determination of ibezapolstat’s ability to achieve Clinical Cure of CDI as measured 2 days after 10 days of oral treatment, but also includes assessment of ibezapolstat’s potential effect on reduction of CDI recurrence in the target population. In the event non-inferiority of ibezapolstat to vancomycin is demonstrated, further analysis will be conducted to test for superiority.
